PIG® Adjustable Frame Storm Drain Filter

Finally, a drain insert that won't fall into your catch basin! Innovative design guards your drains with improved filtering of oil, sediment and debris from stormwater runoff.

• Stainless steel adjustable frame adds strength and secures filter in place, so you'll never have to fish out a failed insert again
• Removes oil and holds up to 60 lbs. of sediment, debris and trash; stays in place even when grate is not installed
• Frame easily adjusts by hand to perfectly fit your square or rectangular drains from 24" to 37" W x 35" to 49" L
• Installation, maintenance and removal are now easy, one-person jobs to reduce your labor costs
• Four-stage filtration: PET construction removes contaminants from stormwater at multiple stages, increasing the amount of pollutants captured
• Stormwater flows through drain grate onto fabric shelf (Stage 1), passes over filter ring (Stage 2) into collection bag (Stage 3) and over four sets of filter strips (Stage 4)
• Patented filter ring channels water to center of collection bag to prevent untreated water from escaping through overflow ports
• Filter strips float freely like tentacles to remove hydrocarbons as water moves through collection bag
• Overflow ports help prevent blockage during high water flow
• Heavy-duty straps on all four sides allow easy handling and are visible even with grate in place
• High-visibility straps help inspectors see from a distance that you're proactively managing your stormwater, and serve as a visual reminder for on-site maintenance
• Grommet on bottom of collection bag gives you the option of attaching extra absorbents, filters or other water treatment accessories
• The pore size is 0.074 mm, 74 microns, 0.0029 inches or 200 sieve
